Special Counsel Robert Mueller’s investigation into the possibility the Trump campaign colluded with Russian officials appears to have morphed into an investigation into alleged “obstruction of justice.”

Although liberal pundits and many congressional Democrats have long argued Trump’s decision to fire Comey was, in effect, a move to cover up other potential crimes, there is an ongoing debate among legal scholars over whether a president, the nation’s chief executive, can be charged with obstructing justice after firing a law enforcement official in the executive branch.

If such a scenario is possible, Democrats might want to tread cautiously, because recently revealed information about the FBI’s handling of the Hillary Clinton email investigation suggests President Barack Obama’s administration may have also “obstructed justice” — or, at the very least, had a very strong incentive to do so.

As Andrew McCarthy noted on Tuesday in National Review, a letter issued over the weekend by Senate Homeland Security Committee Chairman Ron Johnson (R-Wis.) discusses a draft of Comey’s statement about the Clinton email investigation that is dated June 30, 2016. This draft differs, at least in one way, substantially from the infamous statement Comey made on July 5, during which he recommended no charges be brought against Clinton for her use of an illegal private email server. In the draft, Comey mentions that President Obama had communicated with Clinton while she served as secretary of state and “was on the territory of … an adversary”:

“We also assess that Secretary Clinton’s use of a personal email domain was both known by a large number of people and readily apparent,” the draft statement reads. “She also used her personal email extensively while outside the United States, including from the territory of sophisticated adversaries. That use included an email exchange with the President while Secretary Clinton was on the territory of such an adversary. Given that combination of factors, we assess it is possible that hostile actors gained access to Secretary Clinton’s personal email account.”

By the time the July 5 statement was issued letting Clinton off the hook, any mention of emails made by Obama to Clinton’s un-secure email account had been removed from Comey’s statement, which is extremely fortunate for Obama, because if he did knowingly discuss classified information with Clinton through unsecured emails, he could also be investigated for violating federal laws forbidding such reckless activity. And there’s evidence Obama may have attempted to cover his tracks by having his e-mails sealed under the guise of executive privilege. McCarthy explains:

“Obama had his email communications with Clinton sealed. He did this by invoking a dubious presidential-records privilege. The White House insisted that the matter had nothing to do with the contents of the emails, of course; rather, it was intended to vindicate the principle of confidentiality in presidential communications with close advisers. With the media content to play along, this had a twofold benefit: Obama was able (1) to sidestep disclosure without acknowledging that the emails contained classified information and (2) to avoid using the term ‘executive privilege’ — with all its dark Watergate connotations — even though that was precisely what he was invoking.”

Obama’s emails were sealed not long after he told CBS News in 2015 he found out about Clinton’s private email server at the “same time everybody else learned it through news reports.” This is important because emails produced by WikiLeaks show top Democrats and members of Obama’s team reacted in a panic to the former president’s false statement. (Remember, we know Obama had personally emailed Clinton’s private email address.) Cheryl Mills, one of Clinton’s top lawyers told John Podesta, “we need to clean this up – he [Obama] has emails from her [Clinton] - they do not say state.gov.” (State.gov indicates an email is an official government email address.)

With all these pieces in place, it’s easy to see why Obama wouldn’t want Clinton to be prosecuted for illegally using a private email server. This isn’t purely speculative. Obama said in an interview with “Fox News Sunday” in April 2016, in the midst of the FBI’s Clinton investigation, he didn’t think the allegations against Clinton were nearly as serious as everyone else did.

“I continue to believe she has not jeopardized America’s national security,” Obama said. “There’s a carelessness in terms of managing emails that she has owned and she recognizes. But I also think it is important to keep this in perspective.”

Then, Obama went on the campaign trail for Clinton, serving as another signal that he didn’t think Clinton “jeopardized America’s national security.”

Of course, just because President Obama wanted Clinton to be cleared doesn’t necessarily mean he acted (and thus “obstructed justice”) to ensure that would happen, but there is much evidence to suggest Comey and his team made up their mind about Clinton long before the investigation was finished. For instance, Comey drafted a statement exonerating Clinton well before he questioned her and more than a dozen other key witnesses. And newly released text messages between Peter Strzok and Lisa Page, former members of Mueller’s investigation team, show they, too, knew Comey wouldn’t recommend charges be brought against Clinton before she was interviewed.

Here’s what we know: (1) It appears that from the start, Comey had no intention of prosecuting Hillary Clinton. (2) Comey’s hand-selected team looking into the Trump and Clinton allegations included numerous members who disliked Trump and had ties to the Democratic Party. (3) If Clinton had been found guilty of mishandling classified information (or even simply charged), President Obama might have also faced intense scrutiny, and possibly an investigation of his own, because Obama also emailed Clinton on her private server. (4) It appears President Obama deliberately tried to use executive privilege to conceal the fact that he had communicated with Clinton via her private email server, which could be a crime if classified information had been exchanged. If those emails didn’t contain important information, why did Obama’s team work so hard to keep them from the public? (5) Comey recommended Clinton not be prosecuted for using an illegal email server.

If all these statements are true — and that appears to be the case, in my opinion — then the only “obstruction”element missing is an actual request by President Obama’s administration (which, remember, ran the Justice Department) for Comey to keep Clinton out of trouble. On that question, no evidence has yet to be revealed that would prove such a directive ever took place. But isn’t there enough evidence here that a directive could have been issued to warrant an investigation? I don’t know, but there’s certainly as much evidence pointing to a Clinton e-mail cover-up as there is evidence of Trump-Russia collusion.

I’m not a lawyer, but I think it would be exceptionally difficult to prove any president is guilty of obstructing justice after “interfering” with an FBI investigation. Presidents are in charge of managing the executive branch, and the Department of Justice and FBI both fall under that umbrella. However, if liberals continue to suggest Trump is guilty of such a crime for firing Comey while he was investigating alleged collusion, then they could end up putting President Obama — who we now know had plenty of good, selfish reasons for ending the Clinton email investigation — in an exceptionally difficult situation.
